I've seen a lot of shenanigans and scams by clubs in Tokyo, but these dudes are close to taking the cake. They employee a staff of females and recruit women to pretend to be customers to scam guys into buying drinks and champagne. It's like robbery. Girls will hug, kiss, and grind guys. The girl or staff will then ask the dudes to buy 300 dollar (30,000 yen bottles) of champagne. And they will lie and say they are single, have no boyfriend, or anything to get guys to buy champagne. Girls will stroke a guy's penis until they pull out their credit card. To help the scam along, they will try to get the guy drunk or other females will wait until they see a guy is drunk. Edited- Place has changed and stop running this scam, however will update whenever I happen to go there again.
